Percent_diff query with Graphite/Grafana

Is there a way to get the equivalent Graphite metric query that the Grafana alerts are using for percent_diff?

I’ve googled around and found various message board topics but can’t find/figure out how to get a query that gives me the exact same value as the alert query.

Basically: how can I express ( percent_diff () OF query (A, 10m, now) ) as a Graphite metric query?

Thanks in advance!

Following up with this … anyone? bump!

Same here!
